Python 3.6

There are N guests who are invited to a party. The K-th guest will attend the party at time Sk and leave the party at time EK Write a function: def solution(S, E) that, given an integer array S and an integer array E, both of length N, returns an integer denoting the minimum number of chairs you need such that everyone attending the party can sit down. For example, given S1,2,6,5,3] E-[5,5,7,6,8] There are five guests attending the party. The first guest will arrive at time 1. We need one chair at time 1 The second guest will arrive at time 2. There are now two guests at the party, so we need two chairs at time 2 The fifth guest will arrive at time 3. There are now three guests at the party, so we need three chairs at time 3 The fourth guest will arrive at time 5 and, at the same moment, the first and second guests will leave the party. There are now two (the fourth and fifth) guests at the party, so we need two chairs at time 5. The third guest will arrive at time 6, and the fourth guest wil leave the party at the same time. There are now two (the third and fifth) guests at the party, so we need two chairs at time 6 So we need at least three chairs, your function should return 3. Assume that: is an integer within the range [1..500]; each element of array S is an integer within the range1..999]; N . each element of array E is an integer within the range 2..1,000 every person leaves after he/she arrives (S[K]
